  Scouting Report & Links      
         
  Physical Description: Athletic frame. Slightly undersized. Sturdy, filled out. Minimal remaining projection. Runs with a limp and cannot bend right leg due to a childhood injury as a result of which his right leg is shorter than his left. Condition does not limit him at all on the mound or when fielding his position.

Mechanics: Throws from a three-quarters arm slot. Starts on the first base side and has a high leg kick. Significant effort in delivery. Very short stride. Long arm swing behind and then explodes forward with a lightning-quick arm. Back leg does not bend at all during delivery, but still able to drive off it. Will add a trunk twist on some occasions to change his timing when coming to the plate.

Fastball: 96-98 mph. Tops out at 100 mph. Velocity increased substantially in pro ball. Pitch shows life up in the zone, but is on the straight side and plays below its velocity. Command and control are erratic. Potential plus offering.

Splitter: 83-86 mph. Extremely low spin rate. Primary secondary offering. Confidence in and feel for the pitch. Shows late, parachuting movement down in the zone. Has the potential to miss bats at the highest level. Especially effective against left-handed hitters. Did not show the same quality splitter in outings scouted in early 2023. Struggled to land pitch in the zone and throw competitive enough pitches to elicit swings against it, but he only threw it sparingly and therefore may have been throwing less often in order to focus on developing his slider. Feel for the pitch started to come back towards the end of 2023 and it looked more like the pitch he was throwing at the end of 2022. Potential plus pitch if he can consistently throw like he did at the end of 2022 and 2023.

  Slider: 86-89 mph. Longer, 10-to-4 break. Pitch shows two-plane shape and tight rotation at its best. Inconsistent feel at the moment, but on occasion will flash solid potential. Improved considerably in 2023 compared to where it was in 2022, and threw the pitch a lot more frequently. Potential solid-average offering.

Career Notes: Born in the Dominican Republic and moved to Boston as a child. Had surgery on his right knee as a child and required a nine-month hospitalization. As a result, development of the muscles in his right leg was hindered and his knee has very little bend. Participated in the 2021 MLB Draft League. Used six different pitches in college, but the Red Sox asked him to focus on his fastball, splitter, and slider after signing. Team expected him to break camp in 2023 with High-A Greenville, but performed so well in spring training that he was assigned to Portland. Participated in the 2023 Fall Performance Program.

Summation: Potential middle-inning reliever. Ceiling of a late-inning leverage reliever. Has some of the best raw stuff of any relief arm in the system, but needs to improve command and control and consistency. Walks too many hitters and has not missed as many bats in the high minors as he did in the low minors. Splitter is a potential separator pitch with the ability to miss bats at the highest level, but needs to regain his 2022 form with the pitch. Fastball has good velocity, but is hittable and he will have to show the ability to command it to succeed. Has plus makeup and is regarded as one of the hardest workers in the system. Very popular with teammates.
